I have a different issue, on importing 18853 from Log4OM, 17712 have JJ00aa in grid1 field. They are not duplicate QSO. All earlier QSOs have also been filled with this grid.
I then cleaned up all the records with JJ00aa. imported it to a new DXLab suite installed on a different PC. Even then on working a new station not worked earlier this was appearing. Again not on all QSOs.

+ So that I can see what's going on, please attach the ADIF file of 18853 QSOs that you exported from Log4OM to an email message, and send the message to me via
